在 Android 上的 WebView 中阻止 URL [英] Block a URL in a WebView on Android

问题描述

我想阻止在 Web 视图中加载链接.

I want to block a link from loading within a Webview.

代码

public class WebMy extends Activity {


   
    private WebView mWebview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
            setContentView(R.layout.pantalla);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);  
            
    
             
            mWebview  = new WebView(this);
            mWebview.setWebViewClient(new WebViewClient()); 
            mWebview.getSettings().setJavaScriptEnabled(true); // Enable JavaScript.

            mWebview .loadUrl("http://www.myweb.com");
            setContentView(mWebview );
           
    }

潜在解决方案

public class MyWebViewClient extends WebViewClient {
    public boolean shuldOverrideKeyEvent (WebView view, KeyEvent event) {
         // Do something with the event here.
         return true;
    }

    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if (Uri.parse(url).getHost().equals("www.google.com")) {
             // This is my web site, so do not override; let my WebView load the page.
             return false;
        }

        // Reject everything else.
        return true;
    }
}

我不知道如何在我的代码中使用它.例如，如果我想阻止这个 url http://www.myweb.com/pepito.我怎样才能用这个代码做到这一点?谢谢.

I don´t know how I have to use this in my code. For example, if I want to block this url http://www.myweb.com/pepito. How can I do this with this code? Thank you.

推荐答案

shouldOverrideUrlLoading 将检查加载到 WebView 中的网页 URL 和页面内容中加载的所有 URL.

shouldOverrideUrlLoading will examine the web page URL loaded into the WebView and all URLs loaded within the page content.

public class MyWebViewClient extends WebViewClient {
    public boolean shouldOverrideKeyEvent (WebView view, KeyEvent event) {
         
         return true;
    }

    public boolean shouldOverrideUrlLoading (WebView view, String url) {
        if (Uri.parse(url).getHost().equals("http://www.myweb.com/pepito")) {
             // This is my web site, so do not override; let the WebView load the page.
             return false;
        }

        // Reject everything else.
        return true;
    }
}
